Re: Mouse card --- Can EPROM go Bad?

[Wayne Stewart <waynes@intergate.bc.ca>]

My Apple High Speed SCSI cards all use a 27C256 EPROM
the same size of EPROM as my Ramfast SCSI cards.
Considering that my Ramfasts are newer they'd be the last to
die.
Without allowing for me replacing them before they're toast,
the SCSI cards would outlive the computers since they also use
EPROMs of one sort or another. I haven't run across bad
EPROMs in a IIgs yet but I have replaced some in a few II+
and IIe machines.
